Automatic deep web table segmentation by domain ontology

Abstract

For deep web, abundant data information will be presented to users in the form of tables through query forms. Because of the isomerism of data source, to understand and integrate these tables is a very challenging task. This paper proposed a domain ontology based technique for integrating tables. As a method that is completely independent from the structure of tables, it could efficiently solve the nested and conjoined problems existed in complex tables. Experimental results prove that method's effectiveness of improving the accuracy of integration. © 2011 Springer-Verlag Berlin Heidelberg.
